Semantics perhaps, but was backing up the "entire" / filesystem before.
/home, /opt, ... are not part of the / file system in your setup.  I hate
bring up a PC analogy, but what you are asking is "why when I ask it to
backup 'C:' doesn't it also back up my D: & E: drives, and my cdrom, and
my floppy, and my shared network drives?"

I don't think there is a decent way to do what you want with amanda.  Some
people might suggest dynamically 'changing' your disklist each amdump run
according to a scan of your fstab.  But that has problems recently described.

On your system do you have to break things up into separate filesystems?
Why not just have one / filesystem in your fstab?  Then amanda could get it
all with only one disklist entry.
